What do you mean by a tour group flying together?

Refers to a travel arrangement, including round-trip air tickets and related travel services.

During the tour, you will enjoy the round-trip flight service provided by the organizer. This arrangement is suitable for long-distance transnational or transcontinental travel, such as flying from one country or region to another. By booking a "round trip flight", you can get a flight to your destination and return to your original starting point at the same price.
